To all twhom. t may concern.'

Be it known that l. Anrrrnn KUnrrNnn, citizen of the United States, residing at Ell;- ridge, in the county of l-loward and State of Maryland, have invented certain new and useful Improvements in Locomotive Driving Boxes, of which the following is a specification.

This invention relates to an improved locomotive driving box of the general type disclosed in my pending application for similar invention tiled November 20, 15H9, Serial No. 339,347, and has as one of its principal objects to provide a driving box employing a. removable face plate so that the box may, without displacing the locomotive drive wheels, be dismounted and wherein the face plate may be removed with a minimum of difficulty.

The invention has as a further object to provide a driving boX wherein the face pla-te will be formed of companion sections which may simply be displaced laterally in a plane parallel to the outer face of the bon body.

A still further object of the invention is to provide a driving box wherein the sections of the face plate will be securely loclred to the box body and wherein the weight of the load will be utilized for holding said sections against upward movement.

And the invention has as a still further object to provide a driving bei; wherein the face plate will be so formed as to present a continuous wearing surface to the wheely hub.

Other and incidental objects will hereinafter.

is recessed in the usual manner to receive awheel aXle as conventionally illustrated l2 and in the drawings l have indicated the driving wheel at the adjacent end of this axle at 13. lrojecting from the outer side of the box body isan arcuate flange ltand seated within the box body to extend beneath said flange is a crown brass l journaling the axle l2. Projecting from the legs of the box at its outer side are lugs l6 arranged adjacent the lower ends of said legs to depend therebeneath and provided at their upper ends with inwardly and downwardly sloping concave shoulders l? tilted in the direction of the journal receiving recess in the box body. Depending from the legs of the box at its inner side are lugs lS and fitting between the lower end port-ions of the legs is a shelf 19 having lugs 20 mating with the lugs 16 and 1S. Engaging through all of the lugs at the inner side of the bor; is a bolt 2l and engaging through the pairs of lugs at the outer side of the box are bolts 2i As will be perceived, the bolts 2l and 22 will thus serve to rigidly secure the shelf in position so that the shelf will act to tie the legs of 'the box together and brace the legs with respect to each other. Rested upon said shelf between the box legs is grease cellar provided at its inner end with lugs through which are engaged stub `bolts threaded into 'the box body and removably securing the cellar in place.

C'verlying the outer side of the bon is a face plate which is formed of companion semi-circular sections 2li fitting the flange ll and meeting at their ends medially of the box body. Formed on these sections are vertical flanges Q5 overhanging the box body at the outer side thereof and adapted to cooperate with the flanges ll for receiving the legs of a pedestal. At the upper ends of the flanges are provided openings 26 in which a suitable tool may be engaged for removing the sections. Upstanding from the sections at their upper ends are confronting lugs 27 and engaging through these lugs is a tie bolt 28 rigidly connecting the sections. Formed on the lower end portions of the sections at the confronting side edges of the flanges 25 aredownwardly and inwardly sloping convex shoulders Q9 which tit the shoulders 17 of the box body. These shoulders will thus coact for not only securing the lower ends of lthe sections of the face plate against outward movement but will also coact for rigidly lGG llO

securing the lower end portions ot the ilace plate against spreading. Freely lit'ted tl'irough the upper `end portion of the bon body near its upper corners are bolts 30 provided at their outer ends `with lat heads 3l. and, as particularly shown in Figure (5, the heads ot these bolts are formed with oppositely slopingI inner end edges providing at the inner end ott each bolt head reversely presented shoulders rllhe sections of the tace plate are provided in the outer sides thereot with cylindrical recesses ttor freely receiving the bolt heads 3l and enteringn these recesses are slots through which the bolt heads may be projected. Further, the box body l() is provided at its outer side with recesses` 35 into which the bolt heads may be retracted so 'to lie `:[lush with the outer side tace ot the box body. Thus, it will be seen that by retracting the bolts 30 so that the heads thereof will be disposed within the recesses B5, the sections otl they iace plate may be applied and the shoulders 29 thereolI engaged with the shoulders 17 et the lugs 1G. rlhe bols may then be shifted outwardly to project the bolt heads 3l through the slots di of the sections oit the ace plate into the recesses 33, when by rotating the bolts a halt turn the bolt heads will be disposed. to coact withthe bottoni walls oit the recesses so that the nuts upon the bolts may be tightened l'or firmly binding the sections oit the 'Face plate against they boit body. .ln this connectiomit is to be noted that the shoulders 32 et the bolt heads will, when the nuts upon the bolts 30 are rotated, coact with the vbottom walls et said recesses for holding the bolts against rotation so that said nuts may be readily tightened or as easily removed.

Beyond the flanges 25, the lower end portions or' the sections 24 are provided with reduced arcuate extensions 36, theseextensions being thus reduced so as to accommodate the outer end. portion oli the cellar 23 in the rear thereo't and, as particularly shown in Figure 5, said extensions are 'formed with mating beveled edges so that the ends of the extensions are thus overlapped. Uverlying the extensions and. continuing over the outer faces ot the sections ot the tace plate are the substantially semi-circular portions of an annular hub bearing` 37. This bearing is seated in a suitable dove-tailed channel in.

the outer liaces of the sections and, as will` saddle vvhile the mating` recesses 39 and Ll0 are designed to receive the other leg 4t2 of said saddle. The legs of the spring saddle have been. conventionally shown. Thus, as will be seen, the leg l2 will rest partially upon the box body and partially upon the upper ends ot the sections oil the :Face plate so that the weight of the load will be utilized tor holding these sections against upward movement. The bolts 30 will consequently be relieved ol excessive upward stress.

ills will now be readily understood in view ot the preceding descriptionj the lower ends ot the sections ot the face plate will be locked to thebox body by thecoacting shoulders 17 and 29 and will also be locked against spreading` by said shoulders. Similarly, the upper ends of the sections of the tace plate will be locked. to the box body by the bolts 30 while these bolts in conjunction with the tie bolt 28 will serve to lock the upper ends ot the sections against spreading. l he bolts will also serve to resist upward thrust against the sections of the face plate and such. upward thrust will also be resisted by the load upon the spring` saddle. The sections of the tace plate will thus be ell'ectually maintained in position. However, to remove the face plate, it simply necessary to relieve the spring saddle oi' the loadv thereon when, by removing the tie bolt 2S and retracting the `heads 31 ot the bolts 3l into the recesses 35 oit the box body, the sections of the tace plate may simply be shifted laterally and thus displaced, it being noted that the sections ol the face plate may be thus moved laterally in a plane parallel to the plane of `the outer face of the boX body. The tace plate may thus be displaced with a minimum of diliiculty and when so displaced the box body may, of course, be shifted inwardly through the pedestal and itself displaced.

Having thus described the invention., what is claimed new is:

l. A journal box includinga box body, a face plate secured. to the outer side of the box body and providing a continuous annular hub bearing, and means extendin' through the box body connecting the tace plate therewith and retractable to permit removal. ot the lace plate in a plane parallel to the adjacent 'tace oiI the bo); body.

2. In a journal boX,.the combination of a bon body having flanges thereon, a sectional .tace plate seating against the outer side of and overhanging` the 'box body to provide `flanges disposed to cooperate with said first mentioned flanges for operatively receiving a pedestal for the box, and means connecting the plate sections with the box body and retractable to permit lateral removal oit said sections in a. plane parallel to the adjacent tace oF the box body.

3. ln a journal box, the combination of a box body, a face plate seating against the outer side thereof, the face plate being formed ot sections, and means extending through the box body to coact with said sections individually for securing the sections in position and retractable to permit lateral removal of the sections in a plane parallel to the adjacent tace of the box body.

a. In a journal box, the combination of a box body, a face plate seating against the outer side thereof, the tace plate being formed of companion sections coacting at their lower ends to provide a lapped joint therebetween, and means extending through the box body connecting the face plate therewith and retractable to permit lateral removal ot said sections in a plane parallel to the adjacent face of the box body.

5. In a journal box, the combination of a box body, a face plate seating against the outer side thereof, the face plate being formed of sections having laterally directed extensions thereon meeting to provide an annular hub bearing, and means connecting the sections 'with the box body, the extensions being reduced in thickness to accommodate the outer end of a grease cellar fitting between the legs of the box body.

G. In a journal box, the combination of a box body having pedestal flanges, a face plate seating against the outer side of and overhanging the box body providing pedestal flanges to cooperate with said i'irst mentioned flanges, the face plate being formed of sections having laterally directed extensions thereon extending toward each other in a direction between the legs of the box body to provide an annular hub bearing, and a grease cellar disposed between the legs of the box body supporting said extensions l against inward lateral thrust.

In testimony whereof I aiix my signature.
